Inserting and Removing Line Numbers (Renumber and Unnumber)

There are editor commands for inserting COBOL line numbers (left-hand side of the code) or Standard line numbers (right-hand side of the code):

• COBOL numbering - line numbers are inserted in the sequence area of the code (columns 1 - 6), starting at 000100 at the first line, and incrementing by 100.

  It is recommended that you use COBOL numbering only if your files are in fixed or variable source format.

• Standard numbering - line numbers are inserted immediately to the right of area B, in columns 73 - 80, starting at 00001000 at the first line, and incrementing by 1000.

  If it recommended that you use Standard numbering only if your files are in fixed format.
